The hardware and software designing of voice guidance system is based on the multi-computer system. Dual-piece STC12C5A60S2 strengthened 51 single-chip computer was utilized as the lower computer. One piece was used to control the dual DC motor and wheel driven car, giving out sound and light signals. Another was utilized to test different voice sensor signals from three positions. According to the difference in the received time of the voice signals, the distance between car and each received positions could be calculated, confirming the position of the moving sound source, and thus the track of the car was determined. Double piece single-chip computers were kept in touch with each other by the mean of wireless communication. The running behavior of the sounded car could be tracked with the up computer at same time. High efficient L293D was driven by DC circuit, improving the utilization efficiency of the power. The localization of the sound source could be achieved by comparing the different time of the sound arrival from the three positions.

Hardware and software of voice guidance system design is complete by using Multi-motor system structure in this design . The lower control system use two piece STC12C5A60S2 enhanced 51 single-chip computer. One piece used to control the dual DC motor wheel drive car, and give out sound and light signals; another test three different positions of voice sensor signal . According to the voice signals received of three positions at different times, calculate the distance between car and each receiver point, confirm the position of moving sound, determine the car's trajectory. Two piece single-chip computer communicate by wireless communication means. Upper machine shows the car running synchronous. DC driver circuit using effective L293D, help improve power utilization. By testing the different time of sound arrival of the three positions to achieve the localization of their sources.
